The Sealey Mini Grease Gun is designed for automotive technicians and hobbyists who require precise, controlled lubrication in tight, hard-to-reach spaces. Its key benefit is the ability to deliver small, accurate amounts of grease where larger, standard-sized guns cannot fit, though its compact 125cm³ capacity means it requires more frequent refilling during heavy-duty maintenance tasks.

The Sealey Mini Grease Gun is rated for a delivery pressure of 1000psi.
Yes, it is designed for manual loading of grease, though cartridges can also be used if they fit the 125cm³ chamber dimensions.
The gun delivers approximately 0.9cm³ per stroke.
No, this model features a rigid extension tube for maximum control and accuracy.
The tool measures 270mm in length.
Due to its 125cm³ capacity, it is better suited for smaller maintenance tasks rather than high-volume industrial lubrication.
Check for air pockets within the grease chamber and prime the pump again to ensure the plunger is engaging the grease.
Ensure the nozzle is screwed tightly onto the extension and that the grease nipple itself is not damaged or obstructed.
Verify that the grease used is of the appropriate grade and not too cold/viscous, which may increase internal friction.
To set up, unscrew the handle assembly, load your chosen grease, and reassemble carefully to avoid cross-threading. Ensure the nozzle is firmly seated on the grease nipple before pumping. Regarding compatibility, this gun is intended for standard greasing applications; avoid using high-viscosity lubricants that may exceed the pressure ratings of the gun. For care, wipe the exterior with a clean shop rag after each use to prevent grit from entering the mechanism. Periodically check the thread connections for tightness and ensure the rigid extension is not bent or obstructed to maintain consistent pressure delivery.
